MELBOURNE, Australia and BOSTON, Aug. 14, 2022 (GLOBE NEWSWIRE) -- Opthea Limited (ASX: OPT; NASDAQ: OPT), a clinical-stage biopharmaceutical company developing novel therapies to treat highly prevalent and progressive retinal diseases, today announced a non-dilutive financing transaction for up to US$170 million from investment funds working with Launch Therapeutics (Launch Tx) to finance and advance the ongoing Phase 3 clinical trials and pre-commercialization activities of OPT-302 for wet age-related macular degeneration (wet AMD). Launch Tx is the recently formed development company backed by funds managed by global investment firm Carlyle (NASDAQ: CG) and its life sciences franchise, Abingworth.

Under the terms of the agreement, the funds managed by Carlyle and Abingworth, in collaboration with Launch Tx, will commit US$120 million in three installments at fixed time points and retain an option to commit another US$50 million, representing total funding of up to US$170 million for Opthea. If OPT-302 is approved in a major market, Opthea will make a milestone payment after regulatory approval and then six subsequent annual fixed success payments and variable success payments of 7% of net sales, with cumulative payments capped at four times the amount funded to Opthea. Opthea retains full worldwide commercial rights for OPT-302 and has the option to prepay its obligations in full at any time.

Details of the US$90M¹ (A$128.57M) private institutional placement and SPP offering launched today have been separately announced.

"Opthea is thrilled to enter this strategic arrangement with Launch Tx, and to receive funding from world-leading investors in Carlyle and Abingworth. This strategic transaction is expected to fund us through Phase 3 topline data expected in mid-2024 and strengthens our strategic position to maximize the value of OPT-302,” said Dr Megan Baldwin, Chief Executive Officer at Opthea. “This transaction with Launch Tx is non-dilutive for shareholders of Opthea, and we are proud to have been selected as Launch Tx’s first partner since its formation.”

Anshul Thakral, CEO of Launch Tx, commented, "We are excited to partner with Opthea on OPT-302, a novel drug candidate that has demonstrated superior visual acuity in Phase 2 trials over standard of care anti-VEGF-A therapy in patients with wet AMD. With this collaboration, we will advance OPT-302 through its ongoing Phase 3 trials and hope to reach regulatory approval in a timely manner, with the intention of bringing this important medicine to patients in need. At Launch Tx, we are committed to working with pharma and biotech partners to expedite late-stage drug development programs. We do this by designing innovative funding models tailored to our partners’ specific needs and leveraging our extensive clinical development, regulatory, and commercialization expertise as needed. This partnership with Opthea is a great example of one such model.”

OPT-302 is a first-in-class intravitreally administered biologic “trap” inhibitor of vascular endothelial growth factors C (VEGF-C) and D (VEGF-D) currently being investigated in two concurrent Phase 3 pivotal registrational trials that will each enroll ~990 treatment naïve patients, in combination with two approved anti-VEGF-A treatments, ranibizumab (ShORe trial) and aflibercept (COAST trial). OPT-302 has the potential to be positioned as complementary and agnostic with any combined anti–VEGF-A therapy for the treatment of wet AMD, a strategy intended to maximize the commercial opportunity for the therapy.  

Global expert in the treatment of retinal diseases and Chief Investigator for the Phase 3 COAST study, Dr. Charles Wykoff, MD PhD, Director of Research, Retina Consultants of Texas, commented, “In a treatment landscape increasingly crowded with biosimilars and long-acting VEGF-A inhibitors, it is exciting to contribute to the advancement of OPT-302, the only investigational agent in late stage development with the potential to improve vision outcomes over standard of care for patients with wet AMD.”

Cooley LLP (US) and Gilbert+Tobin (Australia) served as legal advisors to Opthea. Goodwin Procter LLP, DLA Piper LLP (US) and DLA Piper LLP (Australia) served as legal advisors to Launch Tx.

Additional details regarding the transactions described in this release and related operational updates will be included in a Report on Form 6-K, which Opthea will furnish separately with the U.S. Securities and Exchange Commission and the contents of which will be lodged with ASX in a separate announcement.

About OPT-302

OPT-302 is a soluble form of vascular endothelial growth factor receptor (VEGFR)-3 expressed as an immunoglobulin G1 (IgG1) Fc-fusion protein. It binds and neutralizes the activity of vascular endothelial growth factor (VEGF)-C and VEGF-D on their endogenous receptors, VEGFR-2 and VEGFR-3. Targeted inhibition of VEGF-C and VEGF-D can prevent blood vessel growth and vascular leakage, which contribute to the pathophysiology of retinal diseases including neovascular “wet” AMD.

About ShORe and COAST Phase 3 Clinical Studies

Opthea currently is enrolling patients for its two ongoing concurrent pivotal Phase 3 clinical trials for the treatment of wet AMD. The global, multi-centre, double-masked, sham-controlled Phase 3 ShORe (Study of OPT-302 in combination with Ranibizumab) and COAST (Combination OPT-302 with Aflibercept Study;) clinical trials will each enroll ~990 treatment-naive patients and assess the efficacy and safety of intravitreal 2.0 mg OPT-302 in combination with 0.5 mg ranibizumab (Lucentis®) (ShORe trial) or 2.0 mg aflibercept (Eylea®) (COAST trial), compared to ranibizumab or aflibercept monotherapy, respectively. In addition, extended durability of the OPT-302 treatment effect on clinical outcomes with less frequent every eight-weekly dosing will be compared with OPT-302 administered on an every four-weekly dosing regimen, in combination with each VEGF-A inhibitor. If successful, the investigation of OPT-302 in combination with two approved standard of care VEGF-A inhibitors in the Phase 3 program could enable OPT-302 to be administered with either Eylea or Lucentis which had combined sales for retinal diseases of >USD$12 billion in 2021. The primary endpoint for both trials is the mean change in Best Corrected Visual Acuity from baseline to week 52 for OPT-302 combination therapy compared to anti-VEGF-A monotherapy. Each patient will continue to be treated for a further year to evaluate extended safety and tolerability over a two-year period.

Inherent Risks of Investment in Biotechnology Companies

There are a number of inherent risks associated with the development of pharmaceutical products to a marketable stage. The lengthy clinical trial process is designed to assess the safety and efficacy of a drug prior to commercialization and a significant proportion of drugs fail one or both of these criteria. Other risks include uncertainty of patent protection and proprietary rights, whether patent applications and issued patents will offer adequate protection to enable product development, the obtaining of necessary drug regulatory authority approvals and difficulties caused by the rapid advancements in technology. Companies such as Opthea are dependent on the success of their research and development projects and on the ability to attract funding to support these activities. Investment in research and development projects cannot be assessed on the same fundamentals as trading and manufacturing enterprises. Therefore, investment in companies specializing in drug development must be regarded as highly speculative. Opthea strongly recommends that professional investment advice be sought prior to such investments.
